HIGH WEAR RESISTANT CEMENT BASED SOLIDIFYING MATERIAL AND CEMENT BASED BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a high wear resistant cement based solidifying material and a cement based block by considering the wear resistance in a mortar part by improving problems that the conventional wear resistance improved concrete does not cause difference from the normal concrete because the mortar part is worn with a metallic fiber and a coarse aggregate (crush stone or gravel) part remains in the concerete reinforced by the metallic fiber, or the like, and the same problem occurs in the case using high hardness aggregate.

SOLUTION: The cement based solidifying material contains≥5 wt.% coated aggregate formed by sticking a surface material on the surface of elastic material chips and having≤3 mm particle diameter as an essential component in addition to hard fine aggregate.
